Specification of Letters Patent.

Application filed April 5, 1911. Serial N0. 619,153.

1 '0 all whom, i t may concern Be it known that I, ADOLPH RYDQUIST, ofRochester, in the county of Monroe and State of New York, have inventedcerta n new and useful Improvements in Paper-Dlspensing Apparatus; and Ido hereby declare the following to be a full, clear, and exactdescription of the same, reference bemg had to the accompanyingdrawings, formmg a part of this specification, and to thereference-numerals marked thereon.

The present invention relates to a paper dispensing apparatus, and hasfor its object to provide a mechanism for permitting removal of paperfrom a continuous roll under the control of a feeding device which isnor mally locked, and adapted to be unlocked by a manual operation topermit withdrawal of the paper until the feeding device 1 s again lockedwhen it has moved a definite distance, so that a definite amount ofpaper is released at each manual operation, corresponding to the extentof movement of the feeding device.

To these and other ends the invention consists in certain improvementsand combinations of parts all as will be hereinafter more fullydescribed, the novel features being pointed out in the claims at the endof the specification.

In the drawings: Figure 1 is a vertical section of an apparatus,illustrating one embodimentof the invention, and showing the position ofthe paper feeding roll, immediately after it is released; Fig. 2 is adetail view showing the position of the parts, when the feeding roll hasbeen partially rotated; Fig. 3 is a detail view showing the position ofthe parts upon completion of the rotation of the feeding roll, at whichtime the latter is again locked; Fig. 1 is a detail view showing apossible position of the parts when the manual operating member is givennearly a complete revolution; Fig. 5 is a view in side elevation of thecasing, showing the hinged cover open; Fig. 6 is a sectional view withparts in elevation, on the line {IE-02 of Fig. 1, and Fig. 7 is asectional view on the line y-y of Fig. 1.

Similar reference numerals throughout the several figures indicate thesame parts.

The present embodiment of the invention, is illustrated as applied to acasing comprising a body portion 1 having an up-st-anding back portion 2and slotted sides 3 arranged to support the paper roll. Hingedl ymount-- ed on the body portion 1 is the cover 1, to the sides of whichare pivoted the spring-controlled members 5 having arms (3 arranged toengage the ends of the paper roll supporting shaft so to force the papernormally into engagement with the feeding roll. The feeding device, inthe present embodiment, comprises a roll 7 which is rotatably mounted onthe shaft 8, the latter having a hand piece 9 fixed to one end outsidethe easing. The releasing means preferably consists of a cam wheel 10,fast on the shaft 8,

and having a cam recess 11, a pin and slot connection serving to unitethe cam wheel with a locking disk 12 attached to the end of the feedingroll 7, the disk being provided with a locking recess 13 Attached to thecasing is a locking member, which in the present embodiment, comprises aspring locking arm 14 engaging the edges of the locking disk and of thecam wheel, the arrangement of the parts being such that in normalposition, as shown in Fig. 3, the locking member 1 1 engages reces's 13and the deepest portion of the cam recess 11, thereby holding thefeeding roll against movement.

VVhen it is desired to operate the device,

to permit removal of a portion of the paper, the hand piece 9 is turneda slight dis tance, causing the cam wheel 10 to be rotated, whereby thecam recess 11 engages the locking arm 14: and moves the latter outwardlyfrom engagement with the recess 13, thus permitting movement of thefeeding roll. The paper may then be withdrawn until the feeding roll hasmade one complete revolution, whereupon the locking arm again engagesthe recess 13 and locks the parts. It is to be noted that when tensionis applied to the paper in withdrawing the same, the feeding roll willmove a slight distance while the cam wheel remains stationary, suchdistance being determined by the length of the slot within which theconnecting pin moves, this operation being illustrated by the transitionof the parts from the position shown in Fig. 1 to that shown in Fig. 2.Under any conditions, however, the feeding roll is permitted only onecomplete revolution, unless the hand piece is turned for more than anentire revolution, and if, for instance, the hand piece is operated tomove the cam wheel for almost an entire revolution, as in the positionshown in Fig; 4, subsequent drawing on the paper will move the lockingdisk 12 relatively to cam wheel 1O so as to enable locking of thefeeding roll when the recess 13 reaches the locking arm 14, at whichinstant the parts assume the position shown in Fig. 3.

movement'of the parts, there is provided a.

spring-controlled locking dog 20, which en gages the gear 18.

Iclaim as my invention:

1. In a paper dispensing apparatus, the

I combination with a paper feeding roll, of

a movable locking member arranged in proximity to the feeding roll andnormally in engagement therewith, and a manually controlled cam wheelarranged to engage the locking member and havi a limited movementrelatively to the fee ing roll.

2. In. a paper dispensin a paratus, the combination with a paper geeding roll, of a locking member normally in enga' ement with the feedingroll, and a manual y controlled member carried by the feeding roll andadapted to move the locking member out of engagement therewith, thelocking member again moving into locking engagement with the feedingroll upon a limited movement of the latter.

3. In a paper dispensing apparatus, the combination with a paper feedingroll, of a locking member normally in engagement with the feeding roll,and ,manually controlled releasing means carried by the feeding roll andhaving a limited movement independently of the feeding roll for movingthe locking member out of engagement therewith.
